Some evidence of interbreeding is not conclusive evidence that they were of the same specie.They can be, but even saying "occasionally" is overselling it....and it's phenomenally rare compared to intraspecies breeding between subspecies.
In this case, we see that Hss could and did breed with both Hsn and Hsd (here we are), and the find in the op shows that Hsd could breed with Hsn. All three populations.
Most interspecies breeding attempts lead to nothing, successful attempts most often to sterile offspring. When I say "most"..here, I'm vastly underselling it - but leaving the possibility open.
Between Hss, Hsn, and Hsd..they could interbreed..and their interbreeding did produce viable offspring. Here we and the op find are. That is pretty strong, though, granted..not entirely conclusive.
Quote:Poodle and Great Dane can interbreed (sometimes with human help) and produce similar sex ratio and rate of fertility amongst the offsprings as if each breaded with another like itself. That’s why they are considered to be of the same specie.Theyre considered to be the same species because they are not reproductively isolated (but they're getting there, lol). I doubt that there was anyone breeding us - helping it along...and neither will breed with wolves - despite all three being the same species. Poodles and great danes are both subspecies of wolf. This one should be of particular interest to Min..as the differences between a wolf, poodle, and great dane aren't enough to imply that we need to work on the idea of species, so why would variations within a human subspecies be? I'll say this..the taxonomy of animals has nothing on the taxonomy of plants..which goes well beyond (and under) species.
I want to be very clear.....I'm not classifying the position you're communicating to me as impossible, only stating that it's much more improbable than the subspecies explanation.
